Answers to common questions.
Why am I not receiving reminders?
Enable Reminders in the app and allow notifications in iOS Settings. Check your reminder hours, interval, pause state, Focus and notification summary. Smart, paused and dense schedules use a limited queue; reopen the app by the date shown in Reminder Settings to extend it. Fixed schedules with no more than 60 daily slots can repeat daily when not paused. iOS controls actual delivery.
Can I use the app without an account or internet?
Core water logging, local statistics, tasks and settings do not require an account or an app server. Sending feedback email needs a configured mail app and a connection.
Why did historical goal percentages change?
Historical comparisons use your current daily target. Week and month show the last 7 and 30 days, including today, rather than calendar weeks or months.
How can I remove my records?
Settings → Reset All removes local water records and progress, resets related settings and turns reminders off. Your selected language is retained. This cannot recover previously deleted records. iOS backups are separate and may include app data; manage them in system settings.
Is there cloud sync or Apple Health integration?
Version 1.0 does not provide cloud sync or Apple Health integration. The developer cannot retrieve local water records from a server.
Which languages does the app support?
The app interface supports Japanese, English and Simplified Chinese. Open Settings → Language to change it. 日本語 is the Japanese option in every language.
Does the app provide medical advice?
No. WaterReminder is a personal recording tool, not a medical device. Targets and tips are general references. Choose a target appropriate to your circumstances and any guidance from your healthcare professional.
Need a hand?
Email the developer with your app version, iOS version, what happened, and the steps to reproduce it. Only include information you want to share. The in-app Feedback screen opens an editable email draft; nothing is sent automatically.
App Store launch is being prepared. The app is planned as a paid download in the United States and Japan; final local prices appear in the App Store.
